Rialto Ripples (1917)

There's no tempo on my sheet music. The tempo in the performance is just what sounds good to me. I think this is the only official "rag" Gershwin ever wrote. I don't know of any others, nor does a friend who's a major Gershwin freak - Rialto Ripples is one of his favourite things to play on his piano. I first heard it on the radio while I was driving. I was all agog, but I didn't catch the name though I was pretty sure it must be Gershwin. I called that friend and sang the melody. He identified it as soon as I sang the first measure.
Aside from errors (I hope none), the score is as I have it, except that on some rolled left hand chords, instead of using grace notes, I've used tied small white notes borrowing from the previous measure. That's because I want the end of the roll, not the beginning, to coincide with the corresponding chord in the treble. (one such example is at the end of measure 30). I did the same thing in one other place that's written in the score as grace notes, not a roll, at the end of measure 19. Elsewhere, I've used noteworthy's grace notes, though I personally would prefer that grace notes borrow time from before the main note rather than from the beginning of the main note itself. I had to do some gymnastics to get the upper ornament into notworthy in measures 74. 76, and 82. The sound comes out correctly though the notation is distictly flaky. I had to do what I did because I can't include rests as "chord members" in noteworthy, so I'd have to use another staff otherwise.
Will Donaldson - I don't know how much of a role he played, but the piece is usually casually identified just as Gershwin He may have been the arranger.
